NCI-N87 [N87]人胃癌细胞(2013年新引进)
产品介绍
目录号 Serial | SCSP-534 | 标识符 Identifier | CSTR:19375.09.3101HUMSCSP534 | 描述 Description | 该细胞表面表达糖蛋白癌胚抗原(CEA)和TAG 72,左旋多巴脱羧酶(DDC)表达阴性。血管活性的肠肽(VIP)受体活性极低并缺乏胃泌激素受体。该细胞表达蕈毒碱胆碱受体(muscarinic cholinergic agents),但没有证据表明表达N-myc、L-myc、myb和 EGFR基因。该细胞表达的c-myc和c-erb-B 2 mRNA水平与其它细胞株相似,但不表达N-myc、L-myc、c-cis、IGF-2和胃泌激素释放肽(gastrin releasing peptide)。有报道认为NCI-N87细胞的植板率为4.3%。每个批次均通过本库支原体检测,结果为阴性。经本库STR检测结果无误。STR结果如下:Amelogenin: X,Y;CSF1PO: 8,12;D13S317: 8,11;D16S539: 9,13;D5S818: 12,13;D7S820: 10,11;THO1: 9;TPOX: 9,11;vWA: 15,16 | 动物种别 Organism | 人 | 性别 Gender | 男 | 组织来源 Tissue and Cell Type | 胃;分离自转移灶:肝脏 | 形态 Morphology | 上皮样,贴壁生长 | 培养基和添加剂 Complete Growth Medium and Culture Conditions | 人胃癌细胞NCI-N87完全培养液配方(100 ml): RPMI 1640 Medium (Invitrogen, 11875-093) 88 ml FBS (Gibco) 10 ml Glutamax(invitrogen 35050) 1 ml Sodium Pyruvate 100 mM Solution (invitrogen 11360070) 1 ml 气相:空气,95%;二氧化碳,5%。温度:37摄氏度。 注意事项: 该细胞贴壁较慢,且生长缓慢,建议复苏、传代后让细胞贴壁48h后再进行后续实验操作。细胞最初将附着形成小岛状,然后在这些密集的斑块中增殖,因此很难正确估计汇合度。避免细胞过密生长,及时更换新鲜培养基,以免培养基的pH受到不利影响。该细胞培养时,在培养基中会有一些漂浮细胞和碎片,并且在该细胞中可能会观察到较大的“囊泡”和颗粒状外观,是正常现象。 | 供应限制 Permits and Restrictions | A。仅供研究之用。 | REFERENCE | Park JG, et al. Characteristics of cell lines established from human gastric carcinoma. Cancer Res. 50: 2773-2780, 1990. PubMed: 2158397 NCI-Navy Medical Oncology Branch Cell Line Supplement. J. Cell. Biochem. suppl. 24: 1996. NCI-N87 is a gastric carcinoma cell line derived in 1976 by A. Gazdar and associates at the National Cancer Institute from a liver metastasis of a well differentiated carcinoma of the stomach taken prior to cytotoxic therapy. The tumor was passaged as a xenograft in athymic nude mice for three passages before the cell line was established. |
